Title:
GRINDING AREA NORMAL GRINDING FORCE-BASED HEAVY LOAD GRINDING WHEEL ACHIEVING SELF-ADAPTIVE COOLING
Document Type and Number:
WIPO Patent Application WO/2022/142698
Kind Code:
A1
Abstract:
A grinding area normal grinding force-based heavy load grinding wheel achieving self-adaptive cooling. The heavy load grinding wheel comprises a grinding wheel base body (1), grinding blocks (2), cooling spray bottles (3), spray bottle nozzles (4), plate-shaped heat pipe heat dissipation devices (5), and self-resetting mechanisms (6). During operation, the grinding blocks (2) entering the grinding area are subjected to normal grinding force to extrude the cooling spray bottles while compressing the self-resetting mechanisms, and then a cooling liquid is sprayed out from the spray bottle nozzle. Pressure springs in the self-resetting mechanisms are adjusted to set a normal grinding force critical value, and when the normal grinding force is reduced below the critical value or the grinding blocks are separated from a grinding operating area, the self-resetting device is used to achieve automatic resetting of the grinding blocks, and the cooling spray bottles then stop spraying of the cooling liquid. The grinding wheel is compact in structure, the flow rate of spraying the cooling liquid can be adjusted in real time according to working conditions, the self-adaptive internal cooling of the heavy load grinding wheel is achieved, a cooling effect is improved, the wear rate of the grinding wheel in heavy load grinding is reduced, and the service life of the heavy load grinding wheel is prolonged.
